Entry to all 42 Colorado state parks will free on Nov. 25 as part of a new Colorado Parks and Wildlife program called #FreshAirFriday.

Colorado Parks and Wildlife is offering this opportunity to people who have signed the pledge to head outside on the day after Thanksgiving. On Black Friday, more than 50 retailers in Colorado and nationwide will close their doors to urge people to go outside instead of joining the rush inside to shop.

Great Outdoors Colorado is covering all costs for park access. Activity fees may apply.
